Introduction

Congratulations on your purchase of Extech’s 380340 Datalogger Module. The Datalogger

Datalogger Operation

Note: The Heavy Duty Meters have an Auto-Shutoff feature that automatically turns off the

meter (after 10 to 30 minutes depending on the model). This feature should be disabled

during a datalogging session. Press the ‘RECORD’ button on the meter to disable the Auto-

Shutoff feature.

Automated Datalogging Preparation

This function permits the Datalogger to automatically collect readings at the sample rate

set by the user.

1. Connect the Datalogger's IN port to the Heavy Duty Meter as shown in the

illustration. (The supplied cable connects the Heavy

Duty meter to the Datalogger). Use the Isolated or

Direct (non-isolated) port on the Datalogger as desired.

2. Turn the Datalogger OFF (‘0’ switch position).

3. Slide the Auto/Man/Out switch to the Auto position.

4. Slide the Time switch to the ‘S’ (seconds), ‘M’ (minutes)

or ‘H’ (hours) range position depending on the data

sampling rate desired.

5. If this is the first time the datalogger is being used,

reset (erase) the datalogger's memory per the Reset Function section below.

6. Power the datalogger (slide switch to the ‘I’ position).

7. To set the sample (recording) rate, press and hold the SET button and, while holding

the SET button, press the INC 1 button to adjust the units digit (use the INC 10

button to adjust the tens digit). Release the SET button when complete. You can set

the interval from 1 to 99 seconds, 1 to 99 minutes, or 1 to 99 hours.

Note: Always set the AUTO and TIME switches to the desired setting before turning

on the Datalogger.

Begin Automated Datalogging

1. Press the PAUSE button to begin logging measurements. The PAUSE LED will

switch off and the DATA LED will blink each time a measurement is recorded.

2. Press the PAUSE button a second time to pause datalogging (PAUSE LED lights).

3. Use the PAUSE button to toggle recording ON (resume) and OFF (pause). When

datalogging is resumed, new readings are recorded right where the datalogger left

off so that readings are not overwritten.

RESET Function

The RESET function erases all of the stored Datalogger readings.

1. Connect the datalogger to the meter as previously described.

2. Set the Auto/Man/Out switch to either the AUTO or MAN position.

3. Power the datalogger and the meter.

4. Press and hold the RESET button for approx. 4 seconds, until "00" is displayed.

NOTE: It may take up to three RESETS to clear all the datalogger memory levels. To be

sure, repeat the RESET procedure three times in succession.

V2.0 3/04

FULL Indicator

The FULL indicator lights when 7999 data points have been recorded.

NOTE: Data will remain in memory until the Datalogger is RESET (see previous section) or

until the batteries are removed.

Manual Datalogging

Manual datalogging allows the user to record one reading at a time.

1. Turn the Datalogger OFF (‘0’ switch position).

2. Slide the Auto/Man/Out switch to the MAN position.

3. Power the Datalogger (‘I’ position). Note that it is very important to set the MAN

switch before turning the Datalogger on.

4. Press the PAUSE button to log one measurement.

5. When the Datalogger memory is full (7999 readings), the FULL indicator will light.

6. To erase (reset) the Datalogger memory, refer to the Reset Function section earlier

in this manual.

Transferring Data to a PC

Once data is collected, the next step is to connect the Datalogger to a PC and transfer the

collected readings.

Hardware Connection

Connect the Datalogger’s OUT port to the PC COM

port as shown via the supplied cable (3.5mm phono

to DB-9 cable). Use either the Isolated or Direct (non-

isolated) output port.

WindowsTM Datalogger Software

Install the supplied software from the WindowsTM

program CD-ROM using the instructions provided on

the CD-ROM. The following software screen will

appear.

Begin Data Transfer

To transfer data from a Heavy Duty meter to a PC, follow the instructions shown below:

1. Slide the Auto/Man/Out Datalogger switch to the OUT position.

2. Power the Datalogger.

3. Select COM 1 or COM 2 on the software screen.

4. Type a file name in the Data File Name field on the software screen.

5. Click on the START key in the software window

6. Press the RESET button on the Datalogger to begin the data transfer.

7. The DATA LED will rapidly blink as the data transfer takes place.

8. Press the PAUSE button to halt the transfer.

9. When the Data LED ceases blinking, the data points have been transferred.

10. After the data points have been transferred, turn off the datalogger. Data will

remain in the datalogger as long as the batteries are fresh.

The data points are transferred to the file named in step 4 above. To view the transferred

data, click the VIEW DATA button on the software screen. The file stored on the PC can

now be opened in other applications such as spreadsheet, word-processor, database or

graphics programs.

Battery Replacement

When the Battery Status LED indicator is NOT lit the batteries should be replaced. Slide

the rear battery cover off in the direction of the arrow. Replace the four ‘AA’ batteries and

secure the battery compartment cover.
